No sequencers were used. The set explores an idea to turn environmental sounds directly into music, and so immerse the music completely with the time and space of the performance. All of the notes were derived from various environmental and other recordings (forest, night sound scape, medieval choir, Tibetan choir, sea..) via FFT to MIDI transformation. The concept is originally known as spetral music or spectralism (http://en.wikipedia.org/wiki/Spectral_music).
At certain intervals frequencies from the original sound were transformed into MIDI notes. Several FFT to MIDI modules were triggered in parallel and each had it's own sync time, which was partitioned from the master sync module. The program was realized with Plogue Bidule modular sound processing software.
It's liberating to not having to think about harmony or notation at all, but to just focus on the sound and its transformation. The process is very unpredictable, which keeps attention on the present. The microtonal harmonies may appear wrong, but they are in perfect harmony with the original sounds and realities from which where they are extracted.
The set was performed on StillStream ambient radio (www.stillstream.com), and hosted by Tange on Mysterious Semblance.
